A downtime is scheduled for all HPC systems starting March 14, 2018, beginning at 7:00 A.M.
and scheduled to finish by 5 P.M. The downtime will affect the Oakley, Owens, Ruby clusters.
Login services and access to storage will not be available during this time.
In preparation for the downtime the batch scheduler will begin holding jobs that cannot complete before
March 14 at 7:00 A.M.

We will have rolling reboots of Oakley, Ruby and Owens clusters starting from Monday Feb 5, 2018 to address recent
CPU vulnerabilities. Login nodes will be rebooted first. The rolling reboots won't affect any running jobs,
but users may experience longer queue wait time than usual on all clusters.
We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.

At approximately 8:15 the morning of December 21st, we will be restarting the batch server processes on Oakley and Ruby to apply a patch. This will result in a small window of time when job submission (and other batch commands) will fail. If you experience problems, please wait a few minutes and try again.

An outage of Globus service is scheduled from 11 a.m. to 3 p.m. Saturday,
December 9, 2017 for scheduled upgrades from Globus. Active file transfers
will be suspended during this time and they will resume when the Globus service
is restored. Users trying to access the service at globus.org will see a
maintenance page until the service is restored.

** DOWNTIME EXTENDED TO 7 PM **
A downtime for all HPC systems is scheduled from 7 a.m. to 7 p.m. Tuesday,
December 12, 2017. The downtime will affect the Oakley, Ruby and Owens
Clusters, web portals, and HPC file servers. Login services, including
my.osc.edu, and access to storage will not be available during this time.

We will have rolling reboots of Oakley and Ruby clusters starting
from 8:30AM on Monday October 9, 2017. A rolling reboot of Owens
will be scheduled for a later date. These rolling reboots will
address recent security vulnerabilities patched by RedHat.
These rolling reboots won't affect any running jobs, but users
may experience longer queue wait time than usual on the cluster.
We apologize for any inconvenience this may cause you. Please
contact oschelp@osc.edu if you have any questions.

Availability and Restrictions

A highly optimized implementation of LAPACK is available on all OSC clusters as part of the Intel Math Kernel Library (MKL). We recommend that you use MKL rather than building LAPACK for yourself. MKL is available to all OSC users.
